New Video Card Not Detected After Replacing Trident Card (138667)


The information in this article applies to:

  • Microsoft Windows 95
This article was previously published under Q138667

SYMPTOMS

After you remove a video card with a Trident chip set (which uses the standard Super VGA driver provided with Windows 95) and add a video card compatible with the standard Super VGA video driver, the Add New Hardware Wizard does not detect the presence of the new video card and does not detect that the video card with the Trident chip set has been removed.

CAUSE

Windows 95 does not properly handle the response to the BIOS checksum it performs on video cards with some Trident chip sets. Therefore, Windows 95 assumes the Trident card is still installed.

RESOLUTION

Remove the Trident Super VGA driver in Device Manager, and then use the Add New Hardware tool in Control Panel to manually add the proper display driver or have the new video card detected automatically.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Windows 95. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
